The single speed Kona Cowan (2011) is the middle offering of this line of BMX bikes. In promotion, Kona emphasizes the fact that this model has become stiffer for 2011. The stiff feel stems from a new dropout design, which use three bolts instead of two. To keep the cost of this bike down, the fork has gone from a Marzocchi DJ1 to a DJ2, which still provides lightweight strength. The brakes of this bike have been changed from the Shimano M575 hydraulic system to the similarly performing Avid Juicy 3 hydraulic system. This model is a step up from the base Shonky (2011) model in terms of its lightweight aluminum frame (the Shonky (2011) model's frame is chromoly), higher performing Marzocchi fork (the Shonky (2011) has a DJ3), and double walled Sun Estate rims (as opposed to cheaper Alex rims).
